A Monday night update on the Heat's Summer League victory, Marlins items and a local radio shakeup:

### The Heat's 106-56 thumping of a dreadful Lakers team in Las Vegas was not only immensely impressive but also historic: It was the largest margin of victory ever in an NBA Summer League game. (Do you get a prize for that?)

Here's what was most encouraging: Norris Cole's exceptional work. He was in attack mode throughout, driving to the hoop and drawing fouls or making pinpoint dishes for baskets. He closed with 13 points (three for four from the field, 7 for 9 from the line) and nine assists, and just one turnover.

Some of the assists were highlight-worthy: a bounce pass to Dexter Pittman, a back-door lob to former Duquesne forward Damian Saunders, and another nifty dish to Pittman for a dunk.

"I want to continue to get better so I can have a role," Cole told NBA TV afterward.

### Pittman scored 14 points - including an impressive sweeping hook - but remains a foul magnet, picking up five in 14 minutes. He had one rebound and no blocked shots, but managed to have two of his shots blocked for the second consecutive game.

### Terrel Harris, who shot 4 for 12 in Miami's first game, was more efficient offensively, closing with 13 points (6 for 11 shooting) and three steals. On defense, Harris drew two offensive fouls.

### With Justin Hamilton and Jarvis Varnado sidelined by injuries, Mickell Gladness continues to make a strong case for the Heat's No. 4 center job. He had three blocks in 18 minutes and his 10 points included a snazzy jump hook. "He reminds me a little of Rasheed Wallace," NBA TV's Rick Mahorn gushed.

### Drew Viney, a 6-8 rookie forward from Loyola Marymount, continues to impress (12 points, four rebounds, five assists). He's a very good perimeter shooter and also made an impressive move for a layup. He has led the Heat in plus/minus each of the first two Summer League games, confirming the impression that Miami plays very well with him on the court. (We assume this will be our first and last ever reference to plus/minus in a summer league game.)

### Adrian Thomas, who played what seemed like 14 years at UM (actually, six), hit three three-pointers (in eight attempts) but is obviously a long shot to make the NBA. He spent last season playing for Bakersfield in the NDBL. Saunders, a 6-7 forward who was cut by the Rockets during training camp last year, had 13 points and two blocks.

### Heat assistant David Fizdale, who is coaching Miami's Summer League team, told The Oregonian at the Las Vegas Summer League that he met with Trail Blazers GM Neil Olshey about the team's head coaching job on Sunday but then removed his name from consideration.

"Head coaching will always be there for me," Fizdale said. "I still have a lot to learn from coach Riley, coach Spoelstra, coach Rothstein. I didn't want to waste Neil's time at all, but I'm flattered he would even think of me to interview."

### Marlins manager Ozzie Guillen said before Monday's game that there's "nothing" more he can do to jump-start the team's wheezing offense. "It's on them," he said. "We have everything they ask us to have. When you go to the plate, the video, the hitting coach, the manager can't help."

### The Marlins then scored five runs, a veritable eruption considering the way they've been hitting. Miami entered with a .241 average, which would be lowest in franchise history, and with 337 runs (third worst in baseball, ahead of only the Cubs and Padres). What's more, the Marlins are hitting .201 with runners in scoring position and two outs.

### With his contract expiring, former University of Miami great Michael Irvin left his WQAM-560 talk show on Monday, telling listeners that it "hurts" that his two-year stint on the station has ended.

Irvin’s agent, Steve Mandel, said WQAM wanted to keep the former Dallas Cowboys star but only if he moved from Dallas to South Florida. Irvin “wasn’t prepared” to do that, Mandel said.

After Irvin declined that request, the station asked if he wanted to appear weekly on Joe Rose’s morning show and make other occasional appearances, Mandel said. But Irvin said no.

WQAM general manager Joe Bell said he prefered Irvin do the show from South Florida because it would have been easier to market it.

Irvin, who has been an NFL Network analyst since 2009, plans to explore options elsewhere in the market, with WMEN-640 and WINZ-940 among stations he is expected to approach.

Though 790 The Ticket has an opening, Irvin appears unlikely to end up there in a full-time role. The station is looking at pairing Marc Hochman with either Jon Weiner or Jonathan Zaslow on its morning show.

“I promise you – stay tuned,” Irvin told listeners. “I will find my way back on the air to you.”

He told listeners that leaving WQAM “absolutely hurts” because “I’ve got a season coming up at UM. I wanted to talk you through this season. But business is business. I can’t begrudge anyone. I wish everybody the best.”

Irvin hosted the show for the first year with former TNT NFL analyst Kevin Kiley before Kiley retired last year. This year, his co-host has been South Florida-based WQAM staffer Curtis Stevenson. In January, Irvin’s program was shifted two hours earlier (to 10 a.m. to 1 p.m.).

Jorge Sedano, who left 790 The Ticket’s morning show in April to concentrate on a television career, is the front-runner to replace Irvin. Because of a non-compete clause in his 790 contract, Sedano could not join WQAM until after Aug. 9.

### One other broadcast note: ESPN announced Monday that it will carry the Gators’ first three football games of the season: against Bowling Green at 3:30 p.m. Sept. 1, at Texas A&M at 3:30 p.m. Sept. 8 and at Tennessee at 6 p.m. on Sept. 15.

In past years, CBS often has aired the Gators-Volunteers game as its college football opener. But CBS is opting for Alabama-Arkansas instead in that 3:30 p.m. Sept. 15 slot.

The Gators’ opener will compete with UM’s opener at Boston College at 3:30 p.m. Sept. 1, which will be an ABC regional telecast.
